Claims.

This invention relates to new and useful improvements in photographic printing type. This application is a substitute for my abandoned patent application filed on May 2, 1940, Serial Number 332,915.

The invention has for an object the construction of type which may be assembled and photographically printed or printed with light sensitive materials. Specifically, the invention contemplates so arranging the type that positive nlm, or tracing, or other recordings may be made from the type, and so that prints may be made from these positives.

Still further the invention proposes to characterize the photographic printing type by the fact that it is composed of a. plurality of transparent or translucent blocks having the reverse negatives of symbols or letters, or numerals or drawings, or pictures, or blank spaces on their face.

Another object of the invention resides in the provision of a novel means associated with the edges of the blocks mentioned in the previous paragraph for connecting them together to build up a composition of said blocks.

The blocks, in accordance with the invention, are designed for type setting and may be composed to make up words, sentences, posters, drawings, diagrams and combinations of such compositions. After photographic or other prints have been made from a composition of the blocks, the blocks may be returned to supply bins and are ready to be used for other compositions.

The printing from the photographic printing type may be done by the blueprint method or by any similar or other methods. Many types of prints may be made with this printing set. If a positive film or a-positive tracing is desired from the composition, the same may be produced by the use of a photographic film or sensitized tracing cloth. The result is black lines on a transparent or translucent background. This positive nlm of tracing may be regarded as the original and any type of print may be made from it. These originals may also be kept in stock for the production of such prints in the future. It is also possible to eliminate these originals and make paper prints directly from the reverse negative compositions.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 25 is a perspective view of one of the blocks of the printing type shown in Fig. 24.

The photographic printing type, in accordance 2i! indicates the individual block, generally. The.

six blocks are arranged in two horizontal lines. The blocks may be constructed from Celluloid, or translucent composition materials, or other materials.

A means is associated with the vedges of the blocks for connecting them together to build up a composition of blocks. rIhis means is characterized by the fact that it prevents the passage of light between the adjacent edge portions 'of the blocks. The construction of each block E@ may be understood by examining Figs. 4, 5, 7 and S carefully. Each block is made from four adjacent layers of identical size pieces, which are shifted relative to each other in a specific manner so as to produce projecting anges and grooves on the edges of the block. The second layer gdb is shifted towards the rightand downwards relative to the top layer 2da. The third layer 26e is shifted rearwards of the second layer Mib but has its side edges in the same planes as Ythe side edges of the second layer Zlib. The fourth or bottom layer -lid is shifted downwards and towards the left of the layer 2de. The top face of this block is imprinted,

painted or in any other manner formed with a reverse negative of the symbol, letter, etc., which it stands for.

The blocks 2Q may be set, one into the other to build up the composition as shown in Figs. 4 and 5. When this is doneY it will be found that the flanges and grooves formed by offset arrangement disclosed in Fig. 7 nt each other. The` various layers of the block may be cemented or secured together in any fashion, or if desired the layers may be theoretical in nature and the block yformed of one solid piece and cut out so as to have the edge flanges and grooves.

A frame 2i is provided for holding each composition of blocks. Each frame is formed from two L-shaped pieces 2iEl and 2lb. The ends of the arms of these pieces are formed with mortice and tenons inter-engaging each other, i as clearly shown in Fig. 3. Moreover, the inner sides of the frame are formed with projecting anges 2i@ and recesses 2 ll receiving Yand inter-engaging the complementary flanges and recesses of the edges of the composition of blocks. Frames similar to the frame 2l may be supplied for holding any size of composition produced from any number of blocks.

The frame composition shown in Fig. 3 may be placed Within a conventional photographic printing frame to print the' composition. Figs. 1 and 2 show the 'application of the composition into such a printing frame. This frame is indicated by numeral 2S. Its front face is provided with an opening .243 across which there is a plate of glass The composition shown in 3 is rested on this glass with its top face remote from the glass 25. A sensitized sheet 2t is placed across the top face of the composition. lIhe back 2i' of the printing frame is then placed 'across the back of the sensitized sheet Z. The usual spring clip 28 is then engaged in position to hold the back or" the printing frame in place, The frame with its V.from o-ne block to the other. this form of the invention is similar to the precomposition is then exposed to sunlight, daylight or articial light, the correct period of time, as required for different types of sensitized sheets being printed.

In Figs. 9-ll inclusive a modified form of the invention has been disclosed which is similar to the prior form, distinguishing merely in the fact that provision has been made for connecting the lines between the various blocks Bil/ of the printing type. In this form of the invention the blocks 2Q are shown disclosing a diagram which is formed largely from lines. However, these lines are required to be continued from one block to the other. For this reason the flanges of the blocks 26 are cut out at the points 3o comprising continuations of the lines required to pass In other respects vious form.

vIn Figs. 12-14 inclusive another form of the invention has been disclosed which is similar to the first iorrn of the invention, distinguishing merely in the fact that each block has been provided with keys and complementary recesses adapted to hold adjacent blocks in proper alignment with each other. Each block 2G". is provided with recesses 3l and projections 32 formed on the sides thereof at complementary positions and comprising said keys These recesses and projections are of complementary shapes. The arrangement is such that the blocks may be set together with the flanges engaging the recesses lonly when they are at the proper' alignment to have the projections i engage the recesses 3l. This produces the keying eifect referred to.

In Figs. 15-18 another form of the invention is disclosed which distinguishes from the prior forms in the construction of the means associated with the edgesY of the blocks for connecting them together to build up a composition in a manner so as to prevent the passing of light between the blocks. Specifically, the composition is formed from a group of blocks 33 each of transparent or translucent material and having the reverse negative of a symbol, or letter, or number, or drawing, or picture, or blank space, etc., on its top face. Each block 33 has a strip of felt 3d attached along all of its sides. When adjacent blocks are placed together the felt particles will inter-engage each other so tightly as to prevent the passage of light. Suitable means is associated with each of thel blocks to hold adjacent blocks under pressure, as required.

The holding means referred to in the previous paragraph includes clips 35 mounted on each block and engageable in complementary recesses Sii on adjacent blocks. Each c lipASE comprises a strip of spring steel, or similar material held at its central portion 35a by several fastening elements 35h'. Each spring has itsend portions 35C iiared outwards. and adaptedto engage iiared ends te formed on the sides of the recesses 36. The iiared ends 35 continue into inwardly directed portions 35d. The arrangement is such that adjacent blocks may be'forced together and thespring clips will engage into the recesses Se and clip the sides thereof to hold the blocks together with suiiicient pressure on the felt edge pieces to prevent the passage of light. These blocks may be separated merely by pulling them apart.

The composition is associated with a frame 3i? which is composed from two adjacent L-shaped sections 38a andSBb having mortice and tenori ends. These sections have .felt material Se along their inner edges adapted to engage the felt material along the outer edges of the blocks 33. Moreover, the inner edges of the L-shaped sections 38a and 33h are suitably recessed to accommodate the projecting clips Wherever required. Moreover, the sections 3Sa and 38lo are associated with holding means capable of holding them in position so that the felt strips 39 are pressed against the felt strips 34 of the adjacent blocks. This is accomplished with steel spring strips 43 which are xedly mounted at one of their ends by fastening elements 4| at points on one of the sections and extend over areas ci the other of the sections. These extended portions are formed with coiled ends 42.

Each spring is housed Within a recess 43 formed in the material of the adjacent sections. The springs 43 are capable of holding the sections 38a and 33b with suilicient tension to hold the felt strips S9 and 33 in light restraining conditions.

In Fig. 19 the frame 2| is shown with a plurality of outwardly extending headed Studs 44 for winding a chord, wire, or the like around the frame and for anchoring the chord on the studs 44 and to keep the frame at various size settings. In other respects this form of the frame is similar to that shown in Fig. 6.

The blocks 20 and 20" are shown joined and held in set position by T-shaped guides and Z-shaped end members 46.

In Figs. 24 and 25 blocks 41 are illustrated with velvet or like strips 43, which surround the four sides of the blocks.
